Chapped lips occur when the thin, delicate skin of the lips becomes dry, flaky, or irritated. Unlike the rest of your skin, lips lack oil glands, making them more susceptible to drying out. The severity of chapped lips can range from mild dryness to painful cracks that hinder eating, speaking, and even smiling.
Causes:
Several factors can contribute to dry and cracked lips. Understanding these triggers is the first step toward prevention and recovery.
1. Environmental Factors
– Cold Weather: Winter air tends to be dry, pulling moisture from your lips.
– Wind Exposure: Harsh winds can strip your lips of their natural hydration.
– Sun Damage: Prolonged sun exposure can lead to peeling and painful burns on the lips.
2. Dehydration
– Inadequate water intake causes the body to pull moisture from less essential areas like the lips, leading to dryness and cracking.
3. Lip-Licking Habit
– While it might seem soothing in the moment, licking your lips removes natural oils and exposes them to saliva, which evaporates quickly, making dryness worse.
4. Allergies or Sensitivities
– Ingredients in lip balms, toothpaste, or cosmetics may irritate the lips.
– Certain foods, such as acidic fruits, can also trigger irritation.
5. Nutritional Deficiencies
– A lack of vitamins such as B-complex (especially B2 and B3), zinc, and iron can lead to chapped lips.
6. Medical Conditions
– Angular Cheilitis: Cracks or sores that develop in the corners of the mouth due to bacterial or fungal infections.
– Actinic Cheilitis: A precancerous condition caused by long-term sun damage.
– Chronic Conditions: Diabetes and autoimmune diseases can dry out the skin, including the lips.
